The recessed-key panel interlocking device is intended to provide a mechanical joint that can connect two panels using a single fastening key. Accordingly, the device connects two panels by interlocking uniform gaps and fingers that have been formed on the edges of each panel, by a small cylindrical key that holds them together. To accomplish this, a channel that can hold the key is formed along the edge region of both panels when the panels are oriented normally to one another. Further, when the panels are interlocked, the key is completely recessed within the panel material. Furthermore, while the panel edges that form the joint must be uniformly rectilinear and meet at right angles at the joint itself, beyond the joint they can assume any shape and bend to any angle, so that parts joined by the joint do not have to be panel-shaped or perpendicular to each other overall.

A corrugated portion is formed in one end edge portion of the metallic shaft main body (2), and a triangular corrugated portion (11) is formed in an end edge portion of the shaft auxiliary body (3) on the metallic shaft main body side. The metallic shaft main body (2) and the shaft auxiliary body (3) are integrated by being linearly arranged by way of meshing that brings a side of the triangular corrugated portion (9) on the main body side and a side of the triangular corrugated portion (11) on the auxiliary body side into contact with each other. A fiber orientation angle (θ) of the fiber reinforced plastic of the shaft auxiliary body (3) is set so as to be in the same direction as a direction of stress generated in a hypotenuse of each triangular portion under a torque load state.

A fastener member (10) including: a base portion (11) having a surface (15); and a plurality of locking members (12) vertically provided on the surface, the locking members locking with a subject to be coupled so as to mechanically couple to the subject to be coupled; wherein the locking member includes a shaft portion (20), projecting from the base portion, having a pair of side faces (22A, 22B) that are opposite each other in a first direction (x) and, as viewed from the surface, diverge in a second direction (y) orthogonal to the first direction, and a barbed portion (21) provided on each of the pair of side faces; and, as viewed from the surface, the barbed portion provided on at least one of the side faces of the pair of side faces extends in a direction intersecting the first direction and the second direction.

The invention relates to a fastening system comprising a first component and a second component. The first component comprises a plurality of fastening projections so that in each case two fastening projections enclose a fastening receiver therebetween. The second component comprises a plurality of fastening projections so that in each case two fastening projections enclose a fastening receiver therebetween. In the connected state of the components the fastening projections of the first component are in engagement with the fastening receivers of the second component and the fastening projections of the second component are in engagement with the fastening receivers of the first component. According to the invention, the fastening projections of the first component are provided with compression slots. The fastening system according to the invention has a high degree of ease of operation and permits stable connections.

A construction system uses a comb connector element in combination with flat or generally planar polygonal shapes of various types. The comb connector elements connect to the edges of the planar polygonal shapes. Each comb connector has at least one pair of connector members. Each connector member has a proximal end connected to the polygonal member, and a distal end. Each connector member having a face portion that includes a recess extending from a central region of the face portion. The recess extends to the distal end of the face member.

Key threaded systems that include key threads having a female lock and male key on a two-dimensional plane and in which the female lock envelops the male key when fully engaged and has a shape that creates lateral resistance to separation from the male key when the female lock fully engages the male key.

Retention mechanisms are used for coupling two objects, such as coupling end-of-arm tooling to a robotic arm system. The retention mechanisms may include two mounting members, each of which may be attached to a respective object to be coupled, such as an end effector and a robotic device appendage. The retention mechanisms may use interlocking alternating fingers on each mounting members to cooperatively form a tapered annular channel into which an external retaining ring or disc spring fits and applies pressure to secure the opposing mounting members in tight proximity to each other.

A disconnect shaft for use in an integrated drive generator longitudinally extending between a first end and a second end having a plurality of gear teeth extending longitudinally from a first face disposed at the first end. A cam ledge is at an intermediate location between the first end and the second end. An annular cavity is defined between an inner surface of an inner bore of the disconnect shaft and an outer surface of a radially inner portion of the disconnect shaft. A generator and a method are also disclosed.

A web component suitable for use with a snap-fit assembly is disclosed herein. The web component includes, but is not limited to, a sheet metal member that has a periphery and a first side and a second side. The sheet metal member also includes a plurality of protrusions that extend from a first surface of the first side and from a second surface of the second side. The plurality of protrusions are disposed proximate a portion of the periphery and are configured to engage a female receiver associated with the snap-fit assembly.
